DEMOUNTABLE RIM AND WHEEL FOR AUTOMOBILES AND OTHER VEHICLES.

Application filed December 20, 1922, Serial No. 607,981. Renewed '0ctober, 27, 1924.

T 0 all whom it may conceive: 7

Be it known that I, CLAYTON STUART iVA'rmNs, a citizen of the United States, residing at Vichita Falls, in the county of Wichita and State of Texas, have invented a new and useful Demountable Rim and Wheel for Automobiles-and Other Vehicles, of which the following is aspeciiication.

The invent-ion comprehends a Wheel-of any suitable design provided With the necessary attachments to comprise the mechanism constituting the featuresof this invention; also a tire rim'of any suitable design having the necessary lugs and mechanism arrangedthereon toprovide a method of removing the tire rim from said Wheel by turning one gear Which disengages a certain number of slanting lugs and permits the rim-to be quickly removed.

Another object of the invention is'to provide a deviceof=-tliis-nature, comprising a Wheel of any suitable design; also a tire rinrof any suitable design having a series of slanting lugs arranged therein; also a series-of supporting rollers which provide means of allowing the-tire rim tobe easily turned. A gear 'is arranged between the tire rim and felloe band of said wheel, which is associated .with teeth on said tire A shaft is arranged l) Qt-'\\'OQ11 said =felloe band and said tire rimto'support the aforesaid gear. A square head is-arranged on one end otthe aforcsaidshaft, having a coil spring which holds the square head against a lixed tlangc of the aforementioned felloe band, thus proriding a locking device.

Another object of the invention is to provide a device of this nature avhich is vory simple and practical and can'be manufactured at a very nominal cost.

The nature and advantages oftheinvention will be better understood when the following detailed description is read in. connection with the accompanying drawing. The invention resides in the construction, combination and arrangement of parts as claimed.

In the drawing forming a part of this application, the various parts are referred to by numbers.

Figure 1 is a sectional View showing the gear and locking device.

Figure 2 is a sectional view showing the 5 arrangement of the supporting rollers.

Figure is a View 'showingthe arrange mentofthe slanting lugs.

Figure 4 is-aside view sectioned at various places to show the construction a and general assembly of the device.

1 is -a-tire rim of any suitable design, having a flange Q arranged thereon, forming a part thereof. 3 is a felloe .band mounted on a Wheel. The felloeband 3 is provided with a flange 4 on one side to support the tire rim 1. The felloe band 8 is also provided with a flange 5 to support the flange 2 of the:tire rim. 6 is a bracket or frame whichrhoids the supporting rollers 7. The tire rim 1 is provided vith a certain number of teeth as illus-- trated at 9 in Figure 4. 10isa shaftarranged transversely 1n the felloe band .3, as illustrated in -E1Q11I6 1. 11 is-a square headon-one end ofthe shaft 10, forming a part thereof. 1-2 is a hexagon nut keyed on theother endcfthe-shaft'10. 13 is a sliding gear keyed on the shaft 10 and is associated with the teeth on the tire rim 1, as illustrated at.9. 1% is a coil spring arranged onthe shaft 10 betweenone side of the felloe band 3 and a .pin 15 in the shaft 10. 16 and 17 are guidesarranged on the felloe band 3, as illustrated in Figure 1, and hold the-gear 13 in the proper place. 18 a slanting lug arrangedon the felloe band 19 is a slanting lug-arrangedon the tire rim 1,.associated \viththe slanting lug 18. As shoivnin Fig-.8, lugs 18 and 19 are arranged in .pairs at regular intervals. A slot is-provided in thefelloeband 3, asillustr-ated at 20, in Figure 4-, for the valve stem of a tire.

hen .in position for use thisinvention serves as a very efficient den'iountable rim and .Wheel. When it is desired to remove the tire rim 1 from the felloe band 3 a socket Wrench is placed onthe hexagon nut 12, WlllCl). is keyed on the shaft 10 and by ing lugs 18 and 19 will become disengaged, 105

thus allowing the rim to be easily and quickly removed. hen it is desired to apply the tire rim 1 to the felloe band 3 the rim 1 is placed over the felloe band 3 and is supported by the rollers 7. In placing the 110 pressing inon the shaft 10 the square head rim 1 on the felloe band 3 the teeth 9 arranged on the rim must be in mesh with the gear 13. Then by pressing the shaft 10 in and releasing the square head 11 from the flange a of the felloe band 3 the gear 13 may be turned in a certain direction, which will engage the lugs 18 and 19 and press the rim 1 against the flange 4L and the flange 2 against the flange 5, thus binding the rim 1 securely to the felloe band 3. The rim 1 is prevented from coming loose when the spring ll draws the square head 11 of the shaft 10 in contact with the flange e of the felloe band 3.

While it is believed from the foregoing description the nature and advantages of the device will be readily apparent, I de sire to have it understood that I do not limit myself to vhat is herein shown and described, and that such changes may be resorted to, when desired, as fall within the scope of what is herein claimed.

lVhat I claim is:

1. The combination with a vehicle wheel comprising a felloe provided with side flanges, one of said flanges being inclined outwardly and the other flange being shaped to support a tire rim,'a tire rim having a dependingflange the edge of which is bev eled to correspond with the inclined flange upon said felloe, said felloe and rim having cooperating locking wedges pro dried with co-acting wedging faces, and means for rotating said rim relative to said felloe whereby to bring said wedges into locking relation, of a plurality of U-shaped brackets uponsaid felloe, and rollers in said brackets to support and guide said tire rim.

2. In combination in a vehicle wheel, a felloe band of channel form including a base and side flanges, one of said flanges having an inclined extension directed outwardly with respect to the base and inwardly with respectto the hub of the wheel, the other flange being curved at its outer portion to tit and support a tire rim, said tire rim being provided with a flange directed toward and bearing against the aforesaid inclined extension of the flange on said felloe band, the edge of said. rim flange being suitably beveled to correspond with the inclination of said extension, co-operating locking lugs arranged on the felloe band a d rim respectively, said lugs having coacting wedging faces directed at a slight angle to the plane of the wheel, a toothed rack formed. on the inner face of said rim, a rotatable gear carrying shaft journalled in the flanges of said felloe band and a gear keyed to said shaft and adapted for slight longitudinal movement thereon, limiting guide flanges for said gear formed on said felloe band intermediate the outer flanges, said gear meshing with the teeth on said rack, a squared nut on one end of said shaft keyed thereto whereby the same may be rotated for bringing the aforesaid wedges into and out of co-operative relation, a squared head upon the opposite end of said shaft keyeo thereto, a coiled spring on said shaft, onecnd thereof engaging a vertical flange of said felloe band the other end thereof engaging suitable abutment provided on said shaft and normally holding said squared head of said shaft against a projection and the rim engaging and supporting flange of said felloe band whereby rotation of said gear shaft is prevented when in place.

combination, a channelled felloe band hav; ing side flanges on both sides thereof and arranged at arr-angle to the base of the band, a tire rim having a flange on one side there of associated with a corresponding flange on the felloe band, a toothed rack on said rim facing the felloe band, a shaft arranged transversely of said felloe band and journalled in one of the upstanding flanges thereof, a gear keyed to said shaft and movable longitudinally thereof, said gear mesh ing with the teeth of said rack, one end of the shaft having a square head arranged thereon and a nut keyed on the other end thereof, a coil spring on said shaft bearing at one end against an upstanding flange of the felloe band whereby said head is normally held in contact with said flange thereby locking said gear shaft against rotation,

a plurality of U-shaped brackets upon said felloe band, rollers carried in said brackets and adapted to support said tire rim, a plurality of pairs of co-operating lugs arranged upon said felloe band and rim, said lugs having co-acting wedging faces on one side thereof the faces bein set at an an le to the'central plane of said wheel, said lugs being adapted to force the tire rim against said felloe band when said gear shaft is retated in one direction, and to release the tire lllL when. the gear slaftis rotated in the opposite direction.
